摘　　要：为解决扫描仪特性在色彩空间内的非线性、不一致问题,提出一种自适应的校正方法,首先根据每个输入扫描值,在校正样本集中选取与输入值在设备色彩空间中特性最为接近的样本组成校正样本子集,利用多重回归的方法对输入的扫描值进行校正。实验结果表明,该方法的校正精度比传统校正方法有显著提高。To solve nonlinearity and non-uniformity problems in device color space for scanner, a scanner calibration method was proposed. Based on each scanned input value, the samples consistent with these inputs in the space were selected from calibration sample set as the nearest sample to form a calibration subset. Using this subset, the given scanned values were modified by multiple polynomial regression method. Experiments show that the proposed method possesses higher calibration precision than other methods.
